I've been trying to search for my specific issue, but could not find any that matched. Today maybe 10 miles after filling my tank I got these codes as soon as I restarted my engine:

P0451 - Powertrain
Evaporative Emission Control System Preassure Sensor Range/Performance

P0101- Powetrain
Mass or Volume Air Flow Circuit Range/Performance Problem

P0448 - Powertrain
Evaporative Emission Control System Vent Control Circuit Shorted

P0603 - Powertrain
Internal Control Module Keep Alive Memory (KAM) Error

Here is the freeze frame at the moment:

Vehicle VIN: 1N6AD0EV2BC435338
Vehicle Manufacturer: Nissan
Vehicle Calibration ID: 19CA1A

RH0517

End of report.

If I clear the codes they will pop back after some time. Are all these codes related to the EVAP issue, is it the valve or the canister that is having an issue?

Thanks for the help

Usually they are related. Try cleaning both the valve and canister. If you drive in dusty conditions consistently you'll want to reroute the breather and add a filter as well.

Thanks for the link. I cleaned the valve as soon as I bought it after reading about the issue here. Is there a way to clean the inside of the canister, mine feels to heavy
